Embodiment Construction
[0034] Attached to the following Figure 1-5 This application will be described in further detail.
[0035] The embodiment of the present application discloses a fire protection system for a cable tunnel.
[0036] refer to figure 1 , a cable tunnel fire protection system, comprising a hanger 1, a tank 2 for storing carbon dioxide and a storage tank 3 for storing fire extinguishing agent, the fire extinguishing agent can be dry powder fire extinguishing agent or calcium bicarbonate. The tank body 2 and the material storage tank 3 are made of pressure-resistant stainless steel, and the tank body 2 is fixedly arranged below the material storage tank 3 .
[0037] refer to figure 1 , figure 2 , the hanger 1 includes a fixed rod 11 and a movable rod 12 , and the movable rod 12 slides through the fixed rod 11 . The bottom wall of the movable rod 12 is fixedly connected with the storage tank 3 . The fixed rod 11 is provided with a limiter for limiting the position of the movabl...

The invention relates to a cable tunnel fireproof system, and belongs to the technical field of fire-fighting engineering. The cable tunnel fireproof system comprises a hanger, a tank body and a storage tank; a spray pipe is arranged at the bottom of the tank body, and a sleeve pipe sleeves the spray pipe; an air outlet pipe in communication with the tank body is arranged on the tank body, a valveis arranged on the air outlet pipe, and the end, away from the tank body, of the air outlet pipe is in communication with a first branch pipe and a second branch pipe; the first branch pipe is in communication with the storage tank, and the storage tank is in communication with a conveying pipe; the conveying pipe is in communication with the spray pipe; and the second branch pipe is in communication with the sleeve pipe. When a fire occurs, a fire extinguishing agent in the storage tank forms a gas-solid mixture under the action of high-pressure carbon dioxide gas and then enters the spray pipe, a part of the carbon dioxide gas enters the sleeve pipe and then is sprayed out, and the carbon dioxide gas sprayed out of the sleeve pipe wraps the gas-solid mixture to form a protective layer so that the fire extinguishing agent can smoothly reach a fire source to be attached to a line, and the fire extinguishing effect is effectively improved.
Description
technical field [0001] The present application relates to the technical field of fire protection engineering, in particular to a cable tunnel fire protection system. Background technique [0002] A cable tunnel refers to a corridor or tunnel-like structure used to accommodate a large number of cables laid on a cable support. In addition to better protection of cables in tunnels, cable tunnels also make it easy for people to inspect and maintain cables. Electrical and cable equipment generally use water mist fire extinguishing system. [0003] However, the water in the water mist fire extinguishing system is easy to conduct electricity, and electrical and cable equipment is prone to electrical accidents such as grounding, short circuit, and blasting when exposed to water. low efficiency. SUMMARY OF THE INVENTION [0004] In order to improve the fire extinguishing efficiency of cables, the present application provides a cable tunnel fire protection system. [0005] A cab...
